From 2008 to 2010, Halina was Director of Reception and Ceremonial Affairs at the
Minister of Foreign Affairs. Halina was the Chief of Protocol for Chadian President
Idriss Déby from February 2010 to 2023. On 31 January 2023, he was appointed as Chad's ambassador to China. Upon his appointment as prime minister, several analysts described Halina as a technician without political ambition, who would not compete with Déby. Halina remained loyal to Déby for a long time, and Déby describes him as his "big brother." Among the important issues, he particularly hopes that by 2034, Chad will become independent in terms of energy and organize the African Cup of Nations football tournament. Halina also announces his desire to open dry ports and free zones. ==Personal life==
